Introduction

During this power point I hope to: Inform you of the breeds of swine Show you an entirely new aspect on pigs.

They are not just smelly, stinky, farm animals; or one of the organisms you have to study in biology class.

I hope you enjoy this presentation!

Pigs: We’ll Start in the Beginning

The pig was one of the first animals to be domesticated, probably as early as 7000 B.C.

Pigs were first introduced to North America in 1539 when Hernando de Soto brought them to the Florida mainland

In the early 1950’s, U.S. pork producers concentrated their efforts on developing a leaner type of hog that would meet increasing consumer demands for leaner meat products, which are low in cholesterol and fat.
